Introduction

Just in case you don’t know that much of electronics, I’ll

specify everything in the pictures. If you do know, just

see the pictures, you can ignore the text to save time.

First components

Here is the main board. Hold it as you see in the picture

and place the ceramic capacitor, the electrolytic

capacitor and the 10K resistor in place as shown on the

picture.

The yellow “blob” is the ceramic capacitor

The “black cylinder” is the electrolytic capacitor

The blue “pill” is the resister. You’ll notice that it has a

brown, black, red and gold or silver line. The body of the

resistor can be either blue or yellow.

3

Capacitors and resistors

Bend the wires so that they stay in place while soldering.

Just to save you the trouble of holding the hot

component when soldering. Notice that the square

copper con the lower part of the “C” is where the

negative side of the electrolytic capacitor is placed. The

resistor and the ceramic capacitor have no polarity so

you don’t need to worry about the orientation.

4

After soldering it should look like this. Cut the extra wires

and make the soldering iron as low as possible, or just

don’t make it be too tall. You’ll need that space to put

the battery holder.

5

Placing the microcontroller

Place the socket and if you prefer, mount the

microcontroller on the right away. You have to make sure

that the “little circle” on the upper left of the atty

(Microcontroller) is facing the resistor.

6

Soldering is not that hard now, isn’t it?

7

Headers

Place the headers as shown in the picture. The ten pin

header goes next to the ceramic capacitor and the eight

pin header goes on the microcontroller’s left.

8

By now this is a bit obvious, but anyways, solder the

headers.

9

Power pins

Add the two pins and the jumper. I used the jumper to

make sure they stay in place while soldering. Best of luck.

IMPORTANT NOTE: You should not leave the green

jumper there because it will shorten the power that

could damage the board. If you’re programming the

board (Board connected to the programmer and to the

computer), don’t use the jumper at all.

10

Battery holder

Place the battery holder like this. Make sure that the

rectangle side of the battery holder is placed next to the

sixteen set of holes.

11

Reset button

Finally place the reset button. It’s not that hard, just be

patient.

12

Be very careful while soldering the button. I don’t think

you want to melt the battery holder.

13

The Tinusaur

And there you have it. A beautiful Tinusaur. Happy

programming and prototyping.

14

How the programmer needs to be conected

While connecting the board make sure you don’t have

the jumper placed, or else you could damage the board

while programming.

Very important notes that you should definitely read

External power header (JP1, the one close to the 8-pin

header H1) is to connect external power. DO NOT put a

jumper there that could damage the board.

Battery On/Of header (JP2, the one closer to the mount

hole) is to connect/disconnect battery to/from the

board. DO NOT have this on while connected to the

programmer or external power source there is no circuit

to protect the battery from overcharging.

15

If you're not going to use external power source or

battery on the board don't put any jumper at all.

Note (about external power source): If you're going to

use external power source (JP1, the one close to the 8-

pin header H1) make sure you connect the negative pole

(-) to the outer pin of the header and positive (+) to the

inner.
